Abstract

PURPOSE:To provide a comfortable heating space above a heater by a method wherein air delivery ports formed in a blast panel and being the tips of air ducts are formed in a manner to point to the whole periphery of a blast panel, in a heater comprising a surface form heat generating body, e.g., an electric carpet, and a blast panel. CONSTITUTION:The tip of a first air duct 14 is located approximately at the central part of the one side of a blast panel approximately in the shape of a rectangle on the whole and forms an air suction port communicating with the outside. The inner end thereof is located to the upper part of a blower 6, the open air is sucked with the aid of the blower 6, and dispersed by means of an impeller 17. Air sucked with the aid of the blower 6 flows through a first air duct 14 and delivered in all directions with the aid of the blower 6. The air flows through a second air duct 15 and is discharged to the outside through delivery ports in the four sides of the blast panel. In this process, the air produces hot air by means of a radiation panel 11. This constitution forms a comfortable heating space.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a heater comprising a planar heating element such as an electric carpet and a ventilation panel.

(Prior art) As shown in, for example, Japanese Patent Application No. 63-156081, which has already been submitted by the applicant of the present application, this type of heater has a planar heating element with one side as a heat radiating surface, which generates heat. The other side of the body is used as a heat dissipation surface, an air passage is provided on the other side of the heating element with a bridge interposed therebetween, and air is forcibly blown from a blower into this air passage, so that the air absorbs heat. There are heaters that generate heat convection by flowing heated material into the room from one end of the air duct, creating a comfortable space using radiant heat, conduction heat, and convection heat.

(Problem to be Solved by the Invention) However, in the above heater of the existing layer, the hot air outlet is provided only on one side, two sides, or three sides of a rectangular panel. In order to create a comfortable warm space above the heater, it is best to blow warm air from all around the heater; for example, if it is a rectangular heater, it is better to blow out warm air from all four sides.

The present invention has been devised in view of the above, and its purpose is to provide a heater that can create a comfortable heated space above the heater using hot air discharged from the heater.

(Means for Solving the Problems) The present invention provides a heating element arranged in a planar manner with one side as a heat radiation surface,
In a heater in which a blower is provided in the air passage of a ventilation mantle to which a ventilation panel in which a plurality of air passages are formed is joined to the other surface of the heating element, the air blower is provided on the ventilation panel and at the tip of the air passage. The above objective is achieved by providing a certain air discharge port toward the entire outer periphery of the ventilation panel.

(Function) As described above, in the present invention, warm air is discharged from the entire outer periphery of the heater, so that a comfortable heated space can be obtained above the heater by the discharged warm air.

The figure is an overall view of the heater, Figure 2 is a partially cutaway slope view showing the internal structure, and Figure 3 is a partial cross-sectional view of A-AwA in Figure 1. In these figures, (1) is the heater. So, this heater (1
) is connected to a heat dissipation panel (2) that functions as a heating element and whose upper surface is a heat dissipation surface, and is provided below this heat dissipation panel (2), and has a plurality of air passages, which will be described in detail later. It is equipped with a ventilation panel (3). Further, a part of the corner has a power plug (5), and a controller (4) for turning on/off a switch, controlling temperature, etc. is provided. Further, a blower (6) is provided approximately in the center of the heater (1), that is, approximately in the center of the blower panel (3). As shown in FIG. 2 and FIG.
is configured to follow the rotation of the motor (16).

The heat dissipation panel (2) has a hot wire heater (8) arranged in a planar manner on the top surface of the top plate (7), and a heat-uniforming sheet (9) made of an aluminum sheet and a surface made of polyester or the like on the top surface. The material (10) is laminated and pasted, and the hot wire heater (8
), a heat-uniforming sheet (9), and a surface material (10) constitute a planar heating element (11).

The blower cloak (3) is made of plastic or the like, and includes a second blower passage (15) formed by a rectifier blade (13) that also serves as a strength member and protrudes from the bottom plate (12), and The first blower communicates with the second blower path (15)! (1
4).

Note that the tip of the first air passage (14) is provided approximately at the center of the negative side of the air blow panel (2), which has a generally rectangular shape as a whole, and communicates with the outside to act as an air suction port. The inner end is located above the blower (6), and the outside air is
6) and diffused by the impeller (17).

That is, as shown in FIG. 3, the air sucked in by the blower II (6) flows through the first
The air blower (14) passes through the air blower (14), is sent out to the four sides by the air blower (6), passes through the second air blower path (15), is formed on the four sides of the air blower panel (2), and is sent out to the four sides by the air blower (6). (
15) is discharged to the outside through a discharge port communicating with the hot air, and in this process, the hot air is turned into warm air by the heat dissipation panel (11) and is discharged to the outside.

FIG. 4 shows a plan view showing this state.

(Embodiment 2) FIGS. 5 to 7 show a second embodiment of the present invention. In this embodiment, the air blower I with a built-in controller has a MIX plug (24) in a part of the corner of the heater (20). ! (2
3) is provided, and on the diagonal line thereof, the tip of the first air passage (32) which acts as an air suction port opens in a part of the corner, and the inner end thereof is the air passage 1! (23). In this case, a lip (32a) is provided at the outer end and is partially closed.

The ventilation panel (22) is made of plastic or the like, and has a second ventilation path (
33) are provided in communication with both sides of the first air passage (32), and the tip of the second air passage (33) is connected to the air panel (22).
) are open as discharge ports on the four sides.

The other configurations of the heat dissipation panel (22) are the same as in the first embodiment, and in the figure (25) is a top plate, (26) is a hot wire heater, (27) is a heat-uniforming sheet, and (28) is a surface material. , (29

In operation, according to this embodiment, air is drawn in by the blower (23) through the suction port (34), passes through the first air duct (32), and then into the second air duct (33). However, since the tip of the first air passage (22) is closed, the first air flow! (32), the pressure is applied almost uniformly, and the air is uniformly discharged to the entire outer circumference of the heater using the second air blowing path (33).

According to each of the embodiments described above, one side of the heating element is used as direct heat, and the other side is provided with an air passage, and by blowing air into the air passage, the wind absorbs heat and the heating element is heated. The air is uniformly discharged into the room from the entire surface of the discharge port. Along with this, convection occurs, and comfortable heating is obtained through the three elements of heat radiation, heat conduction, and heat convection.However, warm air flows from the four sides of the heaters (1) and (20).
